Why do people love to just make stuff up when they post? The range is 
4800 to 14400, and that's the full range of most FAX machines. Some go 
up to 33600, but there are lots of problems, and the required modem is 
encumbered, so a free solution isn't possible.

Why of course?

A *lot* of ATAs have very buggy T.38, if they have it at all. Gateways 
aren't much better. You'll find if you try a few Cisco firmware 
revisions that T.38 peformance varies considerably.
